I usually vape 18mg or 12mg nic., and as I am getting more dialed in on my device and creating good thick vapor, I lean towards 12mg more and more. Well, yesterday I decided to drop by Dirtcheap and get a couple bottles of juice. They have a USAmix there that I really like, and they also had an energy drink flavor I wanted to try, but it only came 24mg. I went ahead and got it and filled my tank. Man, there is a lot more throat hit with the higher nic. content! It is almost too much, but still enjoyable as long as I don't hit it hard. I have read that here on ECF, but until I tried it for myself, I didn't realize how much difference it actually made. Go figure!
